In this paper, the authors propose an effective path virtualization using fountain code that provides the data rate as high as possible with satisfying delay and block loss rate constraints to enhance video quality. Basically, fountain code and video codec H. 264 jointly work to efficiently use the path diversity over the existing wireless heterogeneous networks. Finally, the proposed system is implemented and tested in real environments. Nowadays various wireless networks with different characteristics are available to support diverse user applications. For example, UMTS covers wide area but supports low transmission rate while WLAN covers relatively small area but provides high transmission rate. When multiple wireless networks are available, the cooperation among networks is very important.
